Details, Details? That's a pretty cool buggy. Is it more or less in our scale? Materials made from, plastic or diecast? And where should we look for them?

I'd like to have one just for my Jeep and dune buggy shelf.

It looks like 1/24 -1/25 ,but the figures that come with look small . The seats ,winch ,shifter ,and tire look right ,but the steering wheel and gas cans look small. The body is die-cast but the rest is plastic .Found them marked down for 5$ at Wal-Mart. It's something from the Halo game.
